The U.S. gymnast took a selfie video with the Baywatch actor on Snapchat, getting all giggly after he gave her a quick peck on the cheek. The snap comes after she scored her fourth gold medal in the floor exercise Tuesday.

The two have been flirting non-stop on Twitter since the Rio Olympics. It all began when Efron found out that Biles was a huge fan after her appearance on Ellen, where she received a leotard covered with his face. "Thanks for the heads up @TheEllenShow! Good luck at the Olympic trials @Simone_Biles!" he wrote.
